Some good info here, I'm replacing my airtec fmic with the latest grs one. Currently got airtec ic fans and rad on my s2 and coolant temps are great. Use an aftermarket gauge and ive never had it above 92 as the fans kick in early with msd fan switch and wiring loom. My charge temps are high and I can only run 15psi as any more and it will det at high revs. I've modified my ic and radiator brackets so the ic has some of the core showing at the bottom of the bumper and it's moved all the way over to the drivers side and I've moved the rad to the passenger side so it has a fair bit of core showing through the bumper. Just wondering is it possible to put the fans on the back of the rad on an s2 as the turbo and actuator are extremely close to the rad?
